I am installing a Haltech IG5 on my car and require a EA-EL distributor, i was just trying to work out if the EA dizzy has a no.1 cylinder locator signal or not, i am pretty positive that the EL one does, but seing that the EA's arnt sequential, i was hoping that they didn't have the signal.

As the IG5 Won't work correctly on a ford dizzy unless you modify it by changing the pulse from falling to rising and moving the sensor to a different spot, as the homing signal is on the falling side.

If you need a # 1 signal use an MPI dizzy. they have a smaller vane to act as a reference pulse. If you need them o be all the same use a CFI dixxy. The only difference betwen the 2 is that CFI doesn't have the smaller vane since both banks of injectors are common to all cylinders.

I guess if you had to move the signal you could re drill the pin hole at the bottom where the gear drive is but it could be a tricky operation to get it perfect. The other thing you could do is somehow mofify it and shift the TFI unit forward or backward and that will give the same result.

And for the recort EF and EL AREN't Sequrntial. All bank fired till AU

Also - EF is the odd one out as it has coil pack ignition (EDIS) but they went back to dizzy for the EL.

Does anyone know for sure whether the EL dizzy is same as earlier MPI models except CFI? - I ask because I'm running an EL ECU in my ED and altho it runs pretty well I've never been able to make sense of the base timing + she seems down on bottom end compared to the std ECU.
